A TTORNEY Patented Nov. 15, 1932 UNITED STATES BENJAMIN PRIOR, F RIVER ROUGE, ,MIGHIGAN? AIR GOOLED HAIR wavnm 'nnvicn Application filed February 13, 1931. Serial No. 515,477.

My invention relates to anew and useful improvement in an air cooled hair waving device and relates particularly to the cooling of the coil prong or rod on which the hair is wound.

In permanent waving machines as now constructed, the curling rod or prong about It is an object of the present invention to provide in a hair waving machine a mechanism whereby the transmittal of an excessive amount of heat or an uneven amount of heat to one part of the coil of hair which is being curled is prevented.

Another object of the invention is the provision in a hair waving or curling machine of this class of a clamp associated with the coil rod or prong so constructed that sweating of the hair beneath the clamp will be prevented.

Another object of the invention is the provision in a machine of this class of a hair curhng mechanism whereby the curling rod or prong will be cooled at its center so that v the undesirable heating of the coil of hair may be obviated.

Other objects will appear hereinafter.

The invention consists in the combination and arrangement of parts hereinafter described and claimed.

The invention will be best understood by a reference to the accompanying drawing which forms a part of this specification, and in which,

Fig. l is a. side elevational view of a hair waving machine showing the invention ap plied, with parts broken away and. parts shown in section.

Fig. 2 is a top plan view of the coil rod or prong.

Fig. 3 is a view taken on line 33 of Fig. 2. v

Fig.4 is a perspective View of the coilrod or rong.

ig. 5 is an end elevational view of the coil rod or prong with the associated rollers.

Fig.6 is a view taken on line 6-6 of Fig. 3.

Fig. 7 is a longitudinal central sectional view of a modified form of coil rod or prong.

In the drawing, I have illustrated the invention applied to astandard hair waving machine which is supported; by a vertically extended standard 11 which connects to a fitting '12 and serves to support a head 13 ex tending outwardly from which are the cables 14 which serve to support a suitable frame 15 carrying the electric heating elements 16.

Secured to and projecting upwardly from the standard 11 is a bracket 17 which serves to support an electrically operated blower 18 adapted to deliver a blast of air through the tube 19 into the head 20 from which it may pass into the pipe 21 through the flexible connections 22, the pipes 23, and through the passage 24 formed in the coil rod or prong 25. As shown in Fig. 3, the periphery of this 5 prong or rod 25 is cut away as at 26 and on this reduced portion the coil of hair is wound.

A pair of plates 27 and 28 serve as a support for the rollers 29 and 30 which co-opcrate with the coil prong or rod 25. A notch 31 is formed in these plates for reception of the trunnions 32 which project outwardly from the ends of the coil -prong or rod 25. A ratchet wheel 33 is mounted on one end of the coil pron or rod 25 and is engaged by the dog 34 w ich is normally held in engagement therewith by the spring 35. The clamping bar 36 is swingably mounted on the prong or rod 25 and in this clamping bar 36 I have formed a number of openings 37. By directing a blast of air through the prong or rod 25 while in use, excessive heating of the prong or rod is prevented and consequently the disadvantages resulting from the ex-' r cessive heating are overcome and a superior type of hair curling or waving is efiected. The perforations 37 permit a free circulation of air beneath the clamping bar 36 and thus prevent the accumulation of moisture or sweating on the coil of hair. 1 100 prong consisting in delivering through the In Fig. 7, I have shown the prong or coil rod 25 with the passage 24 closed at one end by the plu 38 so that the blast of air delivered into t e passage 34 is forced outwardly through the openings 39 and through the hair coiled thereon,.thus further bringing abouta proper circulation of air through the hair coil and maintaining throughout the depth of the hair coil an even temperature.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. The method of cooling a hair waving prong consisting in delivering through the prong while in use a quantity of cooling fluid.

2. The method of cooling a hair waving prong while in use a blast of air.

3. In a device of the class described: a curling prong having a passage formed therethroughland provided with radially extending openings communicatingwith said passage; a clamping bar swingably mounted on said prong for clamping a quantity of hair thereon; a blast producing mechanism; and means for establishing communication of said blast producing mechanism with said passage for conducting a blast of cooling fluid to said passage.

4. In a device of the class described: a

curlin prong having a passage formed therethrough; a clamping bar swingably mounted on said prong and having a plurality of openings formed therein, said prong being provided with a plurality of radially extending openings communicating with said passage; a blast producing mechanism; and

means for conducting a blast of cooling fluid from said mechanism to said passage.

5. In a device of the class described: a curling prong having a passage formed therethrough; a blast producing mechanism for producing a cooling blast; and means for conducting a blast of cooling fluid from said mechanism to said passage.

In testimony whereofI have signed the foregoing specification.
